Good morning everyone. We are the manufacturer of these quilting templates.
1. Yes, it's true, they don't move when using your rotary cutter.
2. They come in premeasured widths, so there's no need to measure
3. Cut in an efficient manner "using a sharp blade, 6 layers at a time is possible"
4. Cut in a safer manner "no slippery sliding rulers"
Quilt on!
Quilt on!
